标题： A New Coupling Potential for the Scattering of Deformed Light Heavy-Ions

摘要： 本文引入了一种新的耦合势，以解释大量系统在较宽能量范围内的实验数据。在耦合通道形式论框架内，本文首先展示了当反应中的一个核强烈变形时，标准耦合通道理论的局限性，然后证明了通过在耦合通道形式论中使用新的二阶导数耦合势，可以找到轻重离子反应问题的全局解决方案，例如$^{12}$C+$^{12}$C，$^{16}$O+$^{28}$Si 和$^{12}$C+$^{24}$Mg。这种新方法使用恒定或略微依赖于能量的参数，能够一致地改善弹性散射和非弹性散射数据及其激发函数与实验数据的一致性。 显示英文摘要

摘要： This letter introduces a new coupling potential to explain the experimental data over wide energy ranges for a number of systems. Within the coupled-channels formalism, this letter first shows the limitations of the standard coupled-channels theory in the case where one of the nuclei in the reaction is strongly deformed and then, demonstrates that a global solution to the problems of light heavy-ion reactions such as $^{12}$C+$^{12}$C, $^{16}$O+$^{28}$Si and $^{12}$C+$^{24}$Mg can be found using a new second-derivative coupling potential in the coupled-channels formalism. This new approach consistently improves the agreement with the experimental data for the elastic and inelastic scattering data as well as for their excitation functions using constant or slightly energy-dependent parameters.
